j'avais prévenu les gueudins de la puissance, pour les oufs, y'avait le LPUHP qui parallelise 8 LME 49600 et qui est à la fois SE et BAL, et capable d'envoyer 16w ;)
Mais bon, je connais pas de casque dynamique annoncé pouvant prendre plus de 3000mw en input power ... bon par contre en ortho, un LCD2 peut manger plus... à 130db :D
opc a écrit :Not quite... maximum RMS current is 177mA, and maximum voltage is 22VRMS for a maximum power per channel of 3.9W into 125 ohms. That means an absolute maximum of 7.8W of output power per board.
All of these things coming together is exceedingly unlikely, but if you know you have 125 ohm power hungry headphones, then you probably should plan for a 15VA toroid as a minimum.
Generally speaking, I would use a 25VA for everything since they don't cost any more, aren't much larger, and will mean you're covered for power delivery no matter what.
